What a joke.
Anyone seriously think that a flight attendant is going to count what seat a skyjacker was in when he shot a passenger - and in what seat the dead passenger was riding?
The flight recorders from the planes that hit the WTC have yet to be recovered.
If this isn't a hoax, it sure is the next best thing!
Flight attendants know seats pretty well. Plus, 10B may have been the last row in first class or something. But seats are probably how they refer to passengers, and she wanted to give the seat number so that the passenger could be cross-refed with the manifest. I think other stewardesses also gave out seat numbers to the ops centers.
